What are the interior fire egress rules?

• A. Break windows only after extinguishing.
• B. Keep doors closed to confine fire; disable slides.
• C. Evacuate only via one fixed exit; no hose lines needed.
• D. Open doors/windows/hatches and deploy slides; never impede victim egress; have charged hose lines ready when access points open.

Answer: (D)

Interior fire egress rules are about ensuring rapid, safe escape from the aircraft while firefighters establish control. The priority is to open exits and create a clear path for occupants to evacuate, using doors, hatches, or windows as needed and deploying slides at appropriate exits to speed the escape. It’s essential that nothing blocks or delays victims as they move toward an exit. At the same time, firefighters prepare charged hose lines so water is ready to protect and cool the egress path as doors and other openings are made, helping to control heat and smoke as people exit. This coordinated approach supports life safety and provides immediate fire suppression capabilities as access points are opened. Other options fail because they hinder evacuation, confine the fire by keeping exits closed or slides unavailable, or neglect to provide suppression support along the egress routes.
